HELP – How can to do NAT on VLAN address to public IP

I need to access my cctv located in one of my VLAN. How to do this? Do I need to do NAT of the VLAN address to DMZ and then map the DMZ address to the public IP or do i go direct from VLAN to public IP?do I need to do anything on LAN DNS?can I access it by using the public IP since I don’t want to register it on the public DNS?

P/S:the cctv comes with web server so it can be accessed using IE.
